Heating Basement w/o vents


Can a basement be heated without opening any vents from the duct but keeping the ducts "bare"? In other words the ducts are not covered with any ceiling.

No! Vents will be sized to provide the heat needed! Closing them and no heat will be blowen into the room. You will have some heat come off of the duct if it is not insulated but because it will not be blowen into the room the room will not be at temp.

Nope. The warm air in a forced-air system isn't warm enough to have an effect on ambient air temperature in the non-conditioned space it's passing through in the ducting.

True, you ARE losing some heat energy due to the uninsulated/uncovered ducts, but what heat is lost to the sheet metal is quickly attained by the floor above the duct.

Either work in supplies and returns from the existing ductwork to the basement (both at the floor, if possible...and make sure your furnace can handle the extra volume), or add baseboard heat or a gas fireplace, etc.
